Identity management in a networked computing environment

Abstract

An approach for user identity management in a virtualized/networked (e.g., cloud) computing environment is provided. In a typical embodiment, historical command usage within a server environment is analyzed to determine the characteristics of the commands being run against a cloud resource to determine with a confidence rating the likelihood the commands are being executed by a certain user. Such an approach allows for more efficient user identity management in order to optimize cloud security and system administration.

What is claimed is: 
     
       1. A method for identifying an unknown user in a networked computing environment, the method comprising the computer-implemented steps of:
 receiving, by at least one computer device over a network, a set of commands entered by the unknown user in a logged-in environment, the set of commands having a command name and a set of command options; 
 determining, by the at least one computer device, a user style of the unknown user based on an analysis of the set of commands, including detecting a pattern within the set of command options; 
 performing, by the at least one computer device, a matching operation between the user style of the unknown user and a set of profiles of known users in a profiles database, wherein each profile includes a user style associated with each respective known user; and 
 terminating, by the at least computer device, in response to the matching operation not providing a matching user, an access of the unknown user to the logged-in environment in the networked environment. 
 
     
     
       2. The method of  claim 1 , further comprising the computer-implemented step of calculating a confidence level based on the matching operation. 
     
     
       3. The method of  claim 1 , wherein the user style is based on the set of commands received and characteristics associated with the set of commands received. 
     
     
       4. The method of  claim 1 , wherein the set of profiles is based on historical data. 
     
     
       5. The method of  claim 1 , wherein the networked computing environment comprises a cloud computing environment. 
     
     
       6. The method of  claim 2 , further comprising the computer-implemented step of allowing the user to continue entering commands when the confidence level exceeds a predefined threshold. 
     
     
       7. The method of  claim 2 , further comprising the computer-implemented step of implementing at least one action, as set forth in a set of rules, to require the unknown user to provide additional information when the confidence level does not exceed a predefined threshold. 
     
     
       8. A system for identifying an unknown user in a networked computing environment, comprising:
 a memory medium comprising instructions; 
 a bus coupled to the memory medium; and 
 a processor coupled to the bus that when executing the instructions causes the system to:
 receive, over a network, a set of commands entered by the unknown user in a logged-in environment, the set of commands having a command name and a set of command options; 
 determine a user style of the unknown user based on an analysis of the set of commands, including detecting a pattern within the set of command options; 
 perform a matching operation between the user style of the unknown user and a set of profiles of known users in a profiles database, wherein each profile includes a user style associated with each respective known user; and 
 terminate, in response to the matching operation not providing a matching user, an access of the unknown user to the logged-in environment in the networked environment. 
 
 
     
     
       9. The system of  claim 8 , the memory medium further comprising instructions for causing the system to calculate a confidence level based on the matching operation. 
     
     
       10. The system of  claim 8 , wherein the user style is based on the set of commands received and characteristics associated with the set of commands received. 
     
     
       11. The system of  claim 8 , wherein the set of profiles is based on historical data. 
     
     
       12. The system of  claim 8 , wherein the networked computing environment comprises a cloud computing environment. 
     
     
       13. The system of  claim 9 , the memory medium further comprising instructions for causing the system to allow the user to continue entering commands when the confidence level exceeds a predefined threshold. 
     
     
       14. The system of  claim 9 , the memory medium further comprising instructions for causing the system to implement at least one action, as set forth in a set of rules, to require the unknown user to provide additional information when the confidence level does not exceed a predefined threshold. 
     
     
       15. A computer program product for identifying an unknown user in a networked computing environment, the computer program product comprising a computer readable storage device, and program instructions stored on the computer readable storage device, to:
 receive, over a network, a set of commands entered by the unknown user in a logged-in environment, the set of commands having a command name and a set of command options; 
 determine a user style of the unknown user based on an analysis of the set of commands, including detecting a pattern within the set of command options; 
 perform a matching operation between the user style of the unknown user and a set of profiles of known users in a profiles database, wherein each profile includes a user style associated with each respective known user; and 
 terminate, in response to the matching operation not providing a matching user, an access of the unknown user to the logged-in environment in the networked environment. 
 
     
     
       16. The computer program product of  claim 15 , the computer readable storage device further comprising instructions to calculate a confidence level based on the matching operation. 
     
     
       17. The computer program product of  claim 15 , wherein the user style is based on the set of commands received and characteristics associated with the set of commands received.
